Description

Technical Field

[0001] The present application relates to a method for realizing jacquard processing of complex patterns through grouping and standardization, belonging to the technical field of woven fabrics. Background Art

[0002] The jacquard weave and yarn color matching is one of the core technologies of jacquard technology. The jacquard weave and yarn color matching directly affect the quality of jacquard fabrics, such as the quality, beauty and practicality of the fabrics. For complex fabrics with multiple warps and wefts, there are currently two main newer weaving process methods:

[0003] One is to decompose the complex multi-layer image-scene fabric structure into several standardized basic structures, and then use the weaving CAD technology to establish a structure library (such as "Standardized Design of Multi-color Warp Image-scene Fabric Structure, Luo Bingjin et al., "Journal of Textile Research", Vol. 34, No. 5, p41-46). This method uses two processes, "expanding" and "overlapping". The corresponding relationship between the color, structure, shuttle and pattern plate of the design is associated with the needle organization table, but this method needs to be designed separately for different types of structures. The relationship between the design color, needle organization table and shuttle (weft arrangement) is very important. In the above-mentioned weaving CAD technology, it mainly focuses on the functions of graphic design or pattern special effects generation. The colors in the design map correspond to different shuttles and multiple structure structures need to be set. The process designer must have a strong understanding and memory ability, and consider the warp and weft interweaving between each layer of fabric from a three-dimensional spatial thinking. This has increased the entry threshold for jacquard process processing industry personnel to a certain extent, and the skill requirements for jacquard practitioners are relatively high.

[0004] Another method is to use the shuttle area as a mapping buffer in the design, and simplify the relationship between the color of the design image and the shuttle number as follows: Figure 1 As shown: the one-dimensional linear relationship of the design color corresponding to the organization - the organization row corresponding to the shuttle position in the shuttle area - the shuttle position corresponding to the selected weft (such as: "Realization and Application of Simple Design Mode of Multi-warp and Multi-weft Weaving CAD", Yu Xiaohong et al., "Journal of Textile Research", Vol. 41, No. 1, p63-68). This method artificially weakens the relationship between the needle organization table and the shuttle. From a conceptual understanding, it is simpler than the mode of corresponding the design color, needle organization table and shuttle, but it is time-consuming and laborious. The biggest problem is that it is not easy to modify. The subsequent adjustment of the jacquard process is very cumbersome. Each time the process is adjusted, the process must be redesigned. The amount of data required for complex jacquard design processes is huge, for example: the weft deletion processing of cast-in-place fabrics, and the warp deletion processing of partially heavy warp fabrics. Summary of the invention

[0005] In view of this, the present application provides a method for realizing the jacquard process of complex patterns through grouping normalization, which realizes the one-dimensionalization of the relationship between patterns and drafts, greatly reduces the workload when performing multiple weft processing, and improves work efficiency.

[0006] Specifically, the present application is implemented through the following solutions:

[0007] A method for realizing the jacquard process of complex patterns through grouping normalization, taking multi-warp / weft fabrics as the processing object, includes the following steps:

[0008] 1) Determine the group unit size of the weave: According to the warp density and weft density distribution of the fabric, set the number of warp groups and weft groups, which are the warp group capacity and weft group capacity respectively. The group unit size of the weave is established by the warp group capacity and weft group capacity.

[0009] In this process,

[0010] The maximum number of warp arrangements = warp group capacity = the number of columns of the weave group unit,

[0011] The maximum number of weft arrangements = weft group capacity = the number of rows of the weave group unit.

[0012] 2) Design of the draft and grouping initialization: Using pattern weaving CAD as the operation tool, input parameters such as the warp group capacity and weft group capacity obtained in step 1) on the draft setting page to complete the grouping initialization.

[0013] Before grouping normalization, preset the warp group capacity and weft group capacity on the draft setting page. After setting, it automatically generates warp groups and weft groups with the capacity value. The maximum values of shuttle throwing and warping are determined by the capacity value and are not allowed to exceed the capacity value. However, the capacity can be greater than the actual warp and weft weights of the fabric, and the insufficient part is filled with empty warps or empty wefts.

[0014] 3) Design of the grouped weave library: The weaves designed by grouping are used as general weaves, which are applicable to fabrics with different combinations of warp and weft of the same type. When designing the weaves, design according to the interweaving rules of warp groups and weft groups, and make a general weave library of common warp and weft group interweaving situations for convenient later use.

[0015] The group unit of the weave is the smallest unit formed by the interweaving of multiple groups of warps and multiple groups of wefts. For the same set of weaves, the group unit size of the weave is certain. One weave group unit corresponds to a point on the draft. The width of the weave group unit is equal to the number of warp groups, and the height of the weave group unit is equal to the number of weft groups. The corresponding number of warp and weft groups of the weave group unit can be greater than or equal to the actual number of warp and weft used in the fabric to facilitate the establishment of a general weave library. The group unit sizes of the weaves in the same set of weave libraries are the same and can be used as a general standard weave library, which is applicable to processes with the same capacity but different numbers of warp and weft.

[0016] 4) Grouping of warp and weft yarns: Using the parameters entered in step 3) as a filter, switch the textile CAD to the weft color palette page, and use the shuttle throwing function to match the colors of the weft yarns in each weft group to complete the weft grouping; switch the textile CAD to the warp color palette page, and use the warp drawing function to match the colors of the warp yarns in each warp group to complete the warp grouping.

[0017] Arrange the warp and weft yarns according to the yarn function. Specifically, according to the number of warp and weft groups set in the tissue library and the pattern distribution of the design drawing, and according to the color distribution of the design drawing, design the distribution of different weft yarns in each weft group and the distribution of different warp yarns in each warp group respectively, and use empty warps and empty wefts to represent the vacant parts.

[0018] At the same time, the weft yarns of the same shed are grouped into one group, and the different weft and warp yarns that form a complete interlacing rule are grouped into one group, and the different warp and weft yarns that form a complete interlacing rule are grouped into one group.

[0019] 5) Corresponding grouping of design and tissue: The design and the tissue are corresponding through the pattern needle tissue table. Each design point on the design drawing corresponds to a tissue block on the fabric structure. The number of rows of the tissue block is the same as the number of weft groups, and the number of columns of the tissue block is the same as the number of warp groups. Generate a one-dimensional pattern needle tissue table according to the filter mapping, and then it can be woven on the loom.

[0020] The tissue is composed of group units of the same size. One group unit corresponds to Figure 1 a design point. The rows of the group unit correspond to the weft groups, and the columns of the group unit correspond to the warp groups.

[0021] 6) Output of grouped process: Output the loom weaving file according to the corresponding relationship between the design, the tissue, the warp drawing, and the weft selection.

[0022] During the above process, when encountering an empty warp, the pattern board column is automatically skipped, and when encountering an empty weft, the pattern board row is automatically skipped.

[0023] Compared with the traditional process, this solution avoids the two-dimensional or even three-dimensional relationship in which the design points, shuttle throwing, and warp drawing jointly determine the position of the tissue points in the tissue during its unfolding and overlapping process. The pattern and the tissue block are directly mapped in a one-dimensional relationship. The design point corresponds to the tissue block. The horizontal row of the tissue block corresponds to the position of the weft group area, and the vertical column of the tissue block corresponds to the position of the warp group area. And the specific shuttle throwing and warp drawing are only determined by the shuttle throwing color, realizing the grouping of pattern processing. The solution idea is simple. Especially when replacing the fabric within the maximum multiple weft, the operation is simple and the modification range is small.

[0024] Furthermore, as a preference:

[0025] In step 1), when determining the group unit size, either the direct specification method can be adopted, or it can be calculated according to the following method: taking the maximum warp density of the fabric as the warp reference, grouping the warp threads corresponding to the remaining warp densities according to the maximum warp density to obtain the number of warp groups, which is the warp group capacity; taking the maximum weft density of the fabric as the weft reference, grouping the weft threads corresponding to the remaining weft densities according to the maximum weft density to obtain the number of weft groups, which is the weft group capacity. It is also possible to take the warp threads corresponding to the maximum warp density as one warp group. Among the warp groups formed by the remaining warp densities, there should be at least two warp threads with different warp densities, and the sum of their warp densities should be the same as the maximum warp density, so as to achieve the balanced definition and division of the warp groups. The same principle applies to the weft density.

[0026] In step 4), color matching is carried out by group, that is, after completing the color matching of one weft group, then carry out the color matching of the next weft group; correspondingly, after completing the color matching of one warp group, then carry out the color matching of the next warp group.

[0027] In step 4), the maximum capacity of the shuttle throw is the weft group capacity, and the maximum capacity of the warp drawing is the warp group capacity. With such settings, when the product multiplicity changes, it is only necessary to adjust the design parameters in step 3) to achieve overall replacement, reducing the modification workload caused by product specification changes.

[0028] In step 5), the mapping means that a square in the design drawing corresponds to a group of shuttle throws, a group of shuttle throws corresponds to a group of tissues, and the correspondence of the elements in the tissue is completed. The pattern needle tissue table implemented by this mapping method is a one-dimensional relationship, and only one factor, the color in the color matching, affects the pattern needle tissue table.

[0029] In step 6), the tissue includes the background tissue and the pattern tissue. The warp groups and weft groups are carried out separately according to their respective weaving rules to ensure that there is no mutual influence between the multiple structures. For example, for a fabric with a surface layer, a back layer, and several intermediate layer structures, the back layer and the surface layer are respectively woven by two warp groups and two weft groups in cooperation with the corresponding weaving methods, and the intermediate layer is made by the remaining warp groups and weft groups, ensuring that the patterns of the back layer and the surface layer are not affected by the intermediate layer.

[0030] In the above process, auxiliary function needle parameters can also be entered in the weaving CAD and a function needle tissue table can be generated to realize the processing of the function auxiliary needle tissue. In this process, the function needle tissue is sorted by weft group, and the parameters such as the edge needles and color selection of the fabric are corresponding to the jacquard loom. The weft group setting is arranged according to the fabric weft arrangement, so only the mapping relationship with the jacquard needs to be considered, eliminating the problem of the traditional shuttle phase merging.

[0031] When the above - mentioned solution is used for weaving multiple tissues, the pattern needles / cells are calculated according to the warp and weft density values of the fabric surface layer (surface pattern) and the pattern drawing is made. For multi - warp or multi - weft fabrics, multiple groups are set through the weft groups and warp groups, and the knitting structures of multiple groups / multiple layers of tissues are grouped to obtain the pattern needle tissue table. Only one tissue knitting structure needs to be filled in each color block of the pattern. The program first obtains the two - dimensional array number according to the weft group and warp group. The warp row / weft row corresponds to the column / row of the jacquard tissue diagram. If an empty space (weft row Z) is found, the row is automatically discarded, and the remaining rows are stored in the two - dimensional array, greatly reducing the entry threshold of jacquard weaving, improving the design effect of jacquard technology and reducing errors. It makes up for the deficiencies of the laying - in tissue jacquard process. The operations of deleting warp / weft are automatically processed by the program to find empty spaces, eliminating the cumbersome manual deletion operations; it simplifies the setting method of the pattern needle tissue table, making the pattern needle tissue table more intelligent.

[0052] This embodiment takes Figure 1 the ten - layer jacquard baby quilt shown as an example. The finished product of the baby multi - layer quilt has a warp density of 60 threads / cm, a surface warp density of 15 threads / cm, the middle layer has a warp density of 30 threads / cm and is evenly divided into 8 layers, and the back warp density is 15 threads / cm. The warp ratio of these 10 layers is: 4:1:1:1:1:1:1:1:1:4; the finished product has a weft density of 64 threads / cm, a surface weft density of 16 threads / cm, and the middle layer has a weft density of 32 threads / cm and is evenly divided into 8 layers.

[0053] Taking the pattern CAD as the processing software, the scheme is described.

[0054] When processing the ten - layer jacquard fabric using the processing method of this application, the following steps are included:

[0055] Group the finished product structure. Consider the middle 8 layers as two 4 - layer structures, use the tissue to form a 4 - layer weaving structure, with four layers as a group. Thus, the warps are grouped into 4 groups of warps as a whole. Correspondingly, the wefts are grouped into 4 groups of wefts as a whole.

[0056] For existing multi-layer fabrics, the warp density is generally not very high during jacquard weaving. Usually, it only involves up to 4 warp groups at most, that is, the maximum capacity of the warp grouping can be directly set to 4. There are usually 8 weft selection colors in jacquard looms, so the maximum capacity of the weft grouping is 8. However, considering the softness of the finished product, the maximum capacity of the weft grouping in this case is set to 4.

[0057] The maximum number of warp arrangements = warp group capacity = the number of columns of the tissue group unit;

[0058] The maximum number of weft arrangements = weft group capacity = the number of rows of the tissue group unit.

[0059] The fabric tissues created according to the grouping design concept can form a standard tissue library for corresponding specific processes, so they can be reused.

[0060] According to the weft group capacity and warp group capacity parameters, establish a standard tissue library for jacquard fabrics for infants and children's multi-layer quilts. Leave spaces when drawing the warp and throwing the shuttle to achieve the same set of tissues applicable to jacquard processes with different layers.

[0061] When establishing the tissue of the jacquard fabric for a 10-layer infant quilt, for the convenience of subsequent tissue calls, a unified tissue naming rule is adopted. The four groups of warp threads are distinguished by J1, J2, J3, and J4 respectively, and the four groups of weft threads are distinguished by W1, W2, W3, and W4 respectively. The front warp and weft - the back warp and weft adopt rules such as J1W1 - J4W4 (the tissue diagram is as shown in Figure 2 、 3 ), J2W1 - J4W3 (the tissue diagram is as shown in Figure 4 ), J2W2 - J3W3 (the tissue diagram is as shown in Figure 5 ), J4W4 - J1W1 (the tissue diagram is as shown in Figure 6 )... for naming.

[0062] For the grouped process treatment, the designer only needs to design the number of grid points of the warp and weft threads according to the surface warp and weft densities. During the process, there is no need to expand the designer pattern, which is convenient for subsequent sample making or adjusting the designer pattern for other reasons. The designer pattern is designed according to the single - group warp density and single - group weft density. The fabric warp density is 60 threads / cm, the fabric weft density is 64 threads / cm, the number of warp groups is 4, the number of weft groups is 4, the single - group warp density is 15 threads / cm, and the single - group weft density is 16 threads / cm.

[0063] After setting the number of groups, the designer pattern has the capacity of 4 - fold warp groups and 4 - fold weft groups, and 4 groups of empty warps and 4 groups of empty wefts are preset to ensure correspondence with the tissue library established in step 2). One designer point on the designer pattern corresponds to a group unit formed by the interweaving of multiple groups of warp threads and multiple groups of weft threads in the tissue. The number of rows of the group unit is the same as the number of weft groups, and the number of columns of the group unit is the same as the number of warp groups. For the corresponding relationship between the designer pattern parameter settings and the group unit, see Figure 7 。

[0064] Use the shuttle throwing function to implement the setting of the weft filtering rule. The initial weft group is 4, and the maximum value of the weft group selection item in the corresponding program is only 4. Values greater than 4 are not allowed unless the initial weft group capacity is adjusted.

[0065] Switch to the weft color palette, select the 1st weft yarn color, and the weft group will automatically switch to weft group 1. Left-click on the yellow area pointed to by the arrow below the Jacquard pattern to confirm that the 1st weft yarn color is yellow; then select the 5th weft yarn color, and on the premise that the weft group is 1, left-click on the pink area pointed to by the arrow below the Jacquard pattern to confirm that the 5th weft yarn color is pink; then select the 6th weft yarn color, and on the premise that the weft group is 1, left-click on the purplish red area pointed to by the arrow below the Jacquard pattern to confirm that the 6th weft yarn color is purplish red; see the weft yarn colors of weft group 1 as Figure 8 shown. Select the 2nd weft yarn color, and by default, the weft group switches to 2. Left-click on the background color of the Jacquard pattern (white) to confirm that the area corresponding to the 2nd yarn is the area where the background color of the Jacquard pattern is located, that is, the 2nd weft yarn color is fully thrown; select the 3rd weft yarn color, and by default, the weft group switches to 3. Left-click on the background color of the Jacquard pattern (white) to confirm that the area corresponding to the 3rd yarn is the area of the background color of the Jacquard pattern, that is, the 3rd weft yarn color is fully thrown; select the 4th weft yarn color, and by default, the weft group switches to 4. After left-clicking on the background color of the Jacquard pattern, the area corresponding to the 4th yarn is the area of the background color of the Jacquard pattern, that is, the 4th weft yarn color is fully thrown.

[0066] Use the warping function to implement the setting of the warp filtering rule. The initial warp group is 4, and the maximum value of the warp group selection item in the corresponding program is only 4. Values greater than 4 are not allowed unless the initial warp group capacity is adjusted.

[0067] Switch to the warp color palette, select the 1st warp yarn color, and the warp group will automatically switch to warp group 1. Left-click on the background color of the Jacquard pattern (white), and the range of the 1st warp yarn and the corresponding white area of the Jacquard pattern, that is, the 1st warp yarn color is fully warped; after successively selecting the 2nd, 3rd, and 4th warp yarn colors, left-click on the background color of the Jacquard pattern (white) to confirm that the 2nd, 3rd, and 4th warp yarn colors are fully warped, and complete the grouping of the warp.

[0068] In the standard mode, the finished product of this case should throw 6 weft colors, have 10 Jacquard colors, warp 4 groups, and require 4 tables, with a total of 240 organizations to be set (10×6×4), as Figure 9 shown.

[0069] In the grouping mode of this case, throwing 6 weft colors, having 10 Jacquard colors, and warping 4 groups, only 1 table is required, and only 10 organizations need to be set, as Figure 10 shown.

[0070] Among them:

[0071] The final grouping result of the weft group is as Figure 11 shown, and the warps after grouping are asFigure 12 As shown. The established organization is used as a general standard organization library. When redesigning the organization, the colors of the warp and weft can be ignored, and only which group of warp and which group of weft are interwoven on the front and back sides need to be considered. For the specific color combination (such as Figure 13 shown), the organization screening is carried out after the warp drawing and shuttle throwing are completed.

[0072] Base color organization (white area): The warp group 2 and the weft group 3 are woven in a one-over-one-under plain weave pattern on the surface layer, and the warp group 1 and the weft group 4 are woven in a one-over-one-under plain weave pattern on the back layer; the weft group 1 is composed of three-color colored weft yarns changing tracks, and the weft group 2 is a weakly twisted thick yarn, which is split into a plain weave structure of four layers of gauze in the middle. All the weft yarns of the weft group 1 also need to be split into a plain weave structure of four layers of gauze when participating in the weaving of the base color organization. Therefore, the Figure 13 J2W3-J1W4 organization in Figure 14 is used, and the corresponding organization diagram is as

[0073] Weft grouping 4, the organization Figure 4 rows correspond to the weft group 4 columns, as Figure 15 shown. Apply for the target memory array [pattern height][weft group], and perform organization mapping according to the weft group "filter" (that is, the filtering rule of the weft group); correspondingly, the corresponding relationship between the organization diagram and the warp grouping is as Figure 16 shown.

[0074] Track-changing pattern organization: The warp group 1 and the weft group 1 are woven in a one-over-one-under plain weave pattern on the surface layer, and the warp group 2 and the weft group 4 are woven in a one-over-one-under plain weave pattern on the back layer. The weft group 2 is a weakly twisted thick yarn, which is split into a plain weave structure of four layers of gauze in the middle. The weft group 3 also needs to be split into a plain weave structure of four layers of gauze in the track-changing pattern organization. Therefore, the Figure 13 J1W1-J2W4 organization in Figure 17 is used, and the corresponding organization diagram is as

[0075] The pattern points correspond to the group units of the organization. The rows of the organization group units correspond to the weft groups, and the columns of the organization group units correspond to the warp groups. The extra rows or columns are represented by empty wefts and empty warps. According to the machine sample card, the file for loom weaving is output.

[0076] Four groups of effective warp groups are drawn and four groups of effective weft groups are thrown. In cooperation with the standard organization library designed in the above manner, the technological treatment of 10-layer jacquard fabric is realized.

[0077] When one group of warp and one group of weft are removed, that is, only 3 groups of warp and 3 groups of weft are needed. At this time, there is no need to redesign the organization library. Only in step 4), the empty weft information is filled in shuttle throwing, and in step 5), the empty warp information is filled in warp drawing. The unnecessary shuttle throwing in the four groups is replaced with empty wefts (such as Figure 18 shown), and the unnecessary warp drawing in the four groups is replaced with empty warps (such as Figure 19As shown), the original standard tissue library with a capacity of 4 groups can be continued to be used, and the corresponding front-back interweaving method is as Figure 20 shown.

[0078] Similarly, the above method can also be applied to the standard tissue library for 2 groups of warp and 2 groups of weft.

[0079] In the above grouping normalization method of this case, the capacities of the warp and weft groups are set first. The tissue design is based on the capacities of the warp and weft groups. The capacities of the warp and weft groups are also the maximum multi-layer warp and multi-layer weft capacities of the corresponding tissue library. The artistic conception Figure 1 a point corresponds to a group unit of the tissue. The number of rows of the tissue group unit is the same as the number of weft groups, and the number of columns of the tissue group unit is the same as the number of warp groups. The finally grouped tissue forms the standard general module of this type. When the number of warp and weft yarns is different in the same type, only the number of empty warps or empty wefts needs to be adjusted. When generating the weaving data on the loom, it is automatically mapped according to the empty warp or empty weft group, and the tissue points corresponding to the empty warps and empty wefts are automatically deleted. Without repeating and designing the tissue multiple times, the application can be completed.
